Leo DiCaprio wins award, pledges $15 million to the planet

Nothing makes us swoon like a lionhearted climate change warrior. So today’s climate crush should come as no surprise: Leonardo DiCaprio, the celebrity face of fixing our planet. On Tuesday, DiCaprio received yet another award — where does he keep all 100 million of them, an award room? — and pledged $15 million to environmental groups. The award was for his leadership in confronting the climate crisis and was presented at the World Economic Forum’s Crystal Awards in Davos, Switzerland. Mashable breaks down where his donations are going: $6 million to Oceana and Skytruth for Global Fishing Watch $1 million to the Nature Conservancy for Seychelles debt for nature swap $3.2 million to Rainforest Action Network and Haka to protect Sumatran rainforest $3.4 million to Clearwater…

U.S. demonstrates production of fuel for missions to the solar system and beyond

The first U.S. production in nearly 30 years of a specialized fuel to power future deep space missions has been completed by researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee.

Microbes map path toward renewable energy future

In the quest for renewable fuels, scientists are taking lessons from a humble bacterium that fills our oceans and covers moist surfaces the world over. Cyanothece 51142, a type of bacteria also called blue-green algae, produces hydrogen in robust fashion, and scientists have found that it taps into an unexpected source of energy to do so.

Physicists come up with a way to make cleaner fuel cells

An international group of scientists has developed ion-exchange synthetic membranes based on amphiphilic compounds that are able to convert the energy of chemical reactions into electrical current. The new development could potentially be used in fuel cells, and in separation and purification processes.

Promising new prototype of battery

An alternative technology to Li-ion has been designed for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual “18650” format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium. The batteries have displayed performance levels comparable to their lithium counterparts, and this new technology is already attracting industrial interest. It could be used to store renewable energies in the future, say researchers.

Geoengineering simulation lets us play with the future

Wherever you stand on geoengineering — whether you think it’s our only chance of survival or a fast track to extinction — we should at least consider the idea. As I argued last year, just studying geoengineering could teach us a lot about the climate and just talking about it could ease some lingering political tensions around climate change. So in the spirit of keeping all options on the table when it comes to preventing a climate catastrophe, check out this interactive geoengineering simulation from the Geoengineering Model Intercomparison Project. It lets you look at what global temperatures could look like between 10 and 50 years from now, if we decide to jump down the geoengineering rabbit hole. Here are the specifics from Slate: This interactive shows temperature…
